Oh, I see.
I paid for my Lion, as it happens -- it's running on my MacPro.
Anyway, I borrowed a 10.7.0 from a buddy (early adopter) and rebuilt the boot-stick, and I got to the OS X installer (after I disabled the wifi). Now I just have to set up a drive to install to. I see pretty detailed instructions around here, with downloads and all, to help me out, help get the wifi going.
Thanks for the help, all. I 'll let you know how it goes.
Edit: This is "solved" as a boot-stick issue -- do you guys mark threads "Solved" like the fine folk over at the Arch Linux site?
